Abstract: A coil component includes a drum core including a winding core portion, and first and second flange portions; and a first metal terminal which includes a bonding portion, a connecting portion, a mounting portion, an extending portion, and a joining portion. The first flange portion includes a main body portion, an end-surface-side protruding portion protruding from an outer end surface of the main body portion and a bottom-surface-side protruding portion protruding from a bottom surface of the main body portion. In a direction parallel to a second axis, a shortest distance from an end of the end-surface-side protruding portion on the second positive direction side to the joining portion is a first distance. A maximum distance from the end of the end-surface-side protruding portion to a side end surface of the end-surface-side protruding portion is a second distance. The first distance is larger than the second distance.

Abstract: A decrease in mounting strength of a first metal terminal is suppressed in a coil component. A coil component includes a drum core including a winding core portion, first and second flange portions, a first metal terminal attached to the first flange portion, and a first wire. The first flange portion is connected to a first end in a direction along a central axis of the winding core portion. A first connection end of the first wire is joined to the first metal terminal. The first flange portion protrudes outward with respect to the winding core portion in a first positive direction. The first metal terminal includes a bonding portion, a mounting portion, and a coupling portion connecting the bonding portion and the mounting portion. The bonding portion is joined to an outer surface of the first flange portion with an adhesive interposed therebetween.

Abstract: A coil component includes a drum core including a winding core portion, first and second flange portions, a first metal terminal attached to the first flange portion, and a first wire. The first flange portion is connected to a first end of the winding core portion in a direction along a central axis of the winding core portion. A first connection end of the first wire is joined to the first metal terminal, which has a bonding portion that is fixed to an outer end surface. The bonding portion has a facing surface and a recess that is recessed with respect to the facing surface and accommodates an adhesive. When viewed in a direction along a central axis, an area of a region of the recess facing the outer end surface is equal to or larger than an area of the facing surface.
